The pharynx (pl.: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx.
This marked difference between the composition of the alveolar air and that of the ambient air can be maintained because the functional residual capacity is contained in dead-end sacs connected to the outside air by fairly narrow and relatively long tubes (the airways: nose, pharynx, larynx, trachea, bronchi and their branches down to the ...
The difference in size and proportion between some breeds are as great as those between any wild genera, but all dogs are clearly members of the same species. [5] In 2010, a study of dog skull shape compared to extant carnivorans proposed that "The greatest shape distances between dog breeds clearly surpass the maximum divergence between ...

The trachea is the largest tube in the respiratory tract and consists of tracheal rings of hyaline cartilage. It branches off into two bronchial tubes, a left and a right main bronchus . The bronchi branch off into smaller sections inside the lungs, called bronchioles .
The trachea (pl.: tracheae or tracheas), also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all animals lungs. The trachea extends from the larynx and branches into the two primary bronchi.
The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra. [3] [4] This is in line with the sternal angle, but the carina may raise or descend up to two vertebrae higher or lower with breathing. The carina lies to the left of the midline, and runs antero-posteriorly (front to back). [citation ...
The buccopharyngeal fascia is a fascia of the pharynx. [1] It represents the posterior portion of the pretracheal fascia [ 2 ] (visceral fascia) . [ 3 ] It covers the superior pharyngeal constrictor muscles , and buccinator muscle .
